NO SERVICE OR CONTACT

I'm an Mtn customer and is insured with mtn insurance. I have liquid damage to my I-phone. The phone has been booked in. I have tried unsuccessfully to reach insurance to lodge the claim. Their phone system says they are experiencing technical difficulties for the last 5 days. So you can't reach them that way. I have also emailed numerous times with read receipts and then no response. Al I want to know is has the claim been received and what the claim number is and a reference number. And how long the process will take. Their customer service is shocking. As I had no luck I tried the MTN store in Brooklyn to see if they could reach insurance. They said they could do nothing for me as the person who supposedly send in the claim is on training and not in the store today. Worst customer service I have experienced in long time.
